Wolf Hiding Slot by Evoplay

Mystery stacks land as a full column of four identical hidden symbols. On the next spin, they reveal what's underneath - a regular symbol, a Wild, or a Full Moon trigger. Then they nudge down one position, and the row above fills with a new mystery symbol. That cycle repeats for four spins total before the stack slides off the bottom of the grid. So a single stack landing on reel three gives you four consecutive spins where that column keeps revealing and shifting, each reveal potentially different from the last.

Full Moon is where the coin values live. When a mystery stack reveals Full Moon symbols, each position on the grid independently spins to show either a coin value between 1x and 2,500x your bet or a free spins scatter. All coin values displayed get totaled and paid immediately. It works like a mini instant prize round embedded inside the base game - no bonus trigger needed, just the right mystery reveal.

Free spins need three or more scatter symbols to appear across the Full Moon reveal positions and the main grid simultaneously. The round starts with mystery stacks already loaded on reels two and four, and a win multiplier that climbs with each Hidden Feature trigger. Spins are unlimited - they keep going as long as mystery symbols remain active on the reels. Fresh stacks landing during the round extend it further, and the multiplier applies to every win for the duration. Landing additional scatter symbols during the round nudges the mystery reels upward by one position, effectively extending their life on the grid.

The whole setting is a moonlit dark fantasy forest rendered in deep blues and violets. A full moon glows behind rocky, ice-crusted cave walls that border the grid. The premium symbols are animal warriors on shield-shaped tiles - a wolf in blue plate armor paying the highest at 50x for five, a fox in burnt orange, and a cat in teal. Below them sit colored gemstones and four runic shield symbols for the low end. Everything has a cold, slightly menacing tone, like the forest has been frozen mid-battle. The Wolf Hiding Bonus Buy variant offers direct access to the free spins round at 32x, but this base version requires the natural scatter trigger through Full Moon reveals.
